First appearance of the planet Pekoposo. The planet was actually created when Giroro made a typo error on the Telop machine (typing "Pekoposo" instead of "Pekopon").

At one point in this episode, Keroro has Dororo's face censored with a censored sticker via the Telop machine. Later on when the Keroro Platoon successfully invaded Pekopon (which turns out to be Pekoposo), Dororo's face has the censored sticker removed.
